hygiene in liquid feeding

liquid feeding

In modern pig production liquid feeding systems are widely used. The advantage of this production systems take effects only at optimum hygienic conditions. Yeasts and moulds, which grow rapidly in liquid feeding fast, have to be prevented.

fermentation

The fermentation of liquid feed is becoming an ever-more prominent theme in pig production as the fermentation process enables more targeted control of hygiene conditions in liquid feeding. In addition, a targeted fermentation process improves the availability of nutrients, thus reducing feed costs.

Requirements for fermentation

Anaerobic fermenting conditions in an air-free environment

A fermentation substrate that is rich in starch and/or carbohydrates

Raw materials without coarse constituents that are suitable for pumping

A uniform substrate composition

Non-fermented raw materials, pH > 6.0

Fermentation temperature between 20 and 40° C

Low-germ substrate (yeasts)

Optimum pipe and tank hygiene

preservation of total mixed rations (TMR)

In the dairy cattle feed normally the use of a total mixed ration (TMR) is applied, as it is mixed together directly before feeding on a feed trailer. The great advantage of TMR is to ensure that the animal receives a simultaneous supply of nutrients from the feed components, which is of great importance for high yielding dairy cows in relation to a synchronous supply of energy and protein. Furthermore, upon presentation of a TMR cows are no longer able to sort out less tasty food matches.

After mixing the high-energy TMR the process of strenuous reheating may be put into operation. To prevent this the use of acidifiers out of the SCHAUMASIL or SILOSTAR – programme is recommended. To achieve an energy enhancement of the TMR, glucoplastic matters may be added. It is also possible to apply a product combination of glucoplastic matters with acidifiers.

grain, corn and CCM

The feeding of hygienic grain is the basic requirement for a high performance of the animals. Grain has a high natural seed stocking. Bacteria, yeasts and molds threaten the quality of the grain.

With a high water content and natural seed stocking these microorganisms can grow above average. Their metabolism increases the moisture content and the temperature of stored grain. The microbiological spoilage of the grain gets accelerated.
